a - Total PM reduction figures reflect reductions from both tailpipe and crankcase emissions.
b - This verification is conditional. Full verification will be achieved upon completion of additional testing and other requirements.

Note: For after-treatment devices the reductions are based on the installation of retrofits to engines that were originally produced without diesel oxidation catalysts or diesel particulate filters.
